The only game from this list we got in this thread that REALLY require teamwork is Left 4 Dead 1 & 2
On advanced/expert you simply won't survive without your friends even if you are really good at FPS. Other games listed here need teamwork too, but you can be good on your own too.
All bets on Left 4 Dead series.
